To all whom it may concern:

Be it knownthat I, Enwin E. Smelt, Va citizen of the `United States, residing at Pittsburg, inthe county of Allegheny, State of Penns flvania', have invented certain new and, use ul Improvements in Wheel Conlication. t

My invention relates to the construction of wheels, and more artcularly relates to the construction of t e types of car wheels adapted to rotate or turn upon the wheel seat of the axle upon which the wheels are secured.

One-object of my invention `is to provide a wheel of improved construction having novel means whereby' the relatively movable Contactin surfaces of the .wheeland itsaxle ied with oil or other lubricating such surfaces are lubricated in an effective manner, and the loss of lubricating material through leakage is prevented an overcome.

Another object of this invention is to providea Wheel having an axle eye in its hub portion constructed and arranged t securely maintain tlie,- wheel in place and having novel means for storing a supply of liibricant and for preventing displacement of the wheel on the axle to which the wheel is appliedaforuse. y

.A further` object of the invention is in the combinationfand arran ement of the parts foi-min the wheel, as will more fully appear laereixia/ter.`

-Referring to the .drawings formingpart of this specification. Figure 1 is a sectioual elevation of a forged car Wheel constructed and arranged in accordance with 'my in vention. Fig. 2 is a. plan. of the saine. Fig. 3 is a sectional: elevation of a cast car wheel constructed and arranged in accordance Fig. 4 is a `Vsectional elevation of'a for edl car; wheel-showing a modified; cons truetion` `A made i-nA accordance ivitlfrny iri'v'en't'ibi'i".v Fig. 5 isa. sectionaldetail showing a further ii i odifici i tioninfthe construction of the huboffa''wheel also made in accordance with myinventfion; Y In the accompanying drawings. referring i to Figs. 1 and 2. a forgedmetal car wheel is shown having a hub 2 connected b an ini t al'web 3 with'a. tread 4 having a ange 5. Il axle eye in the hub 2 is provided with a removable bushing G having an annular ret p ce '7` opening into the axle eye and forming a cellar or reservoir in which' Va supply of-l oil or other lubricating material' isrn'aiii- 7? tained. `Inserted within' the bushinglf isfll;4 second bushing 8 made in sections rand onefo' section having a closed outr`endf9fanda iiiaigiiial llaiige 10 on its inner'fend'." Two lengthwise separated sections 11 and-'121 are also inserted within the opening in the bush# ing (l and set screwsl are provided on-tlie'` 65 bushing 6 to maintain the sectional innerA bushin in position when assembled in place.

Locate within the sectional bushin formed 'i of the parts 8, 11 and 12 is the 'w eel-'seetof the axle 14 u on which the wheel is rota- 70 tably secured w en in use,the1wheelseat of this axle as shown being provided' withfan .f

` By reference to Fi 1 it will a5 y thedoppositefaces o the collar formed b the ring 16 are in engagement withV the mi Jaceut ends of the parts 8, llzand .12 ofthe inner bushing so as to form Vthrust surfaces which take the side .thrust put .u n the so wheel when in use.

1In :Fi-g.' l1-sa constriiction 105 portion 4 and ange portion 5 are the same as in Fig. 1. The sectional bushing in the eye of the wheel hub in this construction is 1 different in being s lit lengthwise into two-1110 arts. 6* andA 6"` an the so-formed buehi is provided with an annular recess 7 fo g eparts 11- and 12 is split-transver'seljjA t of'its len h to enable theaxleaeyepivith Vits ing a reservoir or cellar in la similar manner to that shown in Figs. 1 and 3. The wheel' seaton the axle 14 is the same as in the preceding figures and a similar thrust ring 16 is provided.

In Fig. 5 a further modification is shown in which the hub portion 2b of a cast wheel is joined by spokes 3" to a tread portion 4" and Hangt rtion 5". In this construction the hub 2b is provided with an annular recess or pocket 7 formingthe oil cellar or res-l ervoir 1n a manner similar to that shown in Fig. 3, the outer end of the axle e e in the hub 2b being provided with a close end 2. A bushing 1S-'which is split lengthwise is inserted in the a-xl'e eye of Vthis Wheel and is securely held in position therein hy means of set screws. 13. This bushing is provided with an 'annular inwardly extending flange 18'* which is adapted to enter the recess 18 formed in the wheel seat of the axle 14" on which the wheel .is mounted so as to provide thrust .surfaces which also serve to maintain' the Wheel in place on the axle 14h. Openings or holes 19 inthe bushing 18 communicate with and connect the oil cellar 7 always being supplied from a pool of lubrivveating material.

Modifications in the construction and arrangement-ofthe parts may be made-withoutdeparting from my invention as defined 'in the claims. The thrust rings may be formed inte al on the axles instead of being shrunk: 1n place as shown in Figs. 1, 2,

,3 and 4. :The number of parts used in forming the bushingfcan be varied and other changesv may be made.

'I claim:

1. 'A wheel comprising ahub, a'sectional bushing in the eye of said hub and turning on the axle 'with the'wheel, the sections of'said bushing having ad'oining end sur--v @faces intermediate the len s of the wheel hub arranged to form an annular recess hub through which lubricant is in and adapted to provide thrust surfaces engaging with ,the side surfaces of the thrust collar on said axle.

2. A wheel comprising a hub, a sectional bushing secured ,in the eye of said hub and turning on the axle with the wheel, said bushing having a closed outer end and hav# ing adJoiningend surfaces intermediate the ends of the wheel hub arranged to form an annular recess therein and adapted to provide .thrust surfaces engaging wit-hthe side surfaces of thethrust collar on said axle.

3. A Wheelcomprising a hub, a sectional bushing secured in the eye of said hub and turning on the axle with said Wheel, said bushing having adjoining end surfaces im termediate the ends of the wheel hub arranged to form an annular recess therein and adapted to provide thrust surfaces engaging with the side surfaces of the thrust collar on said axle, and means for maintaining the sectional bushing in place.

" 4. A wheel comprising a hub, a, sectional bushing in the eye of said hub turning on the axle with the wheel, said bushing having a closed outer end and having adjoining end surfacesjntermediate the ends of the wheel hub arranged to form an annular recessv therein and adapt-ed to provide thrust .surfaces enga-ging with the opposite side surfaces of the thrust collar on the axle, and means for maintaining the. sectional bushing inI place.

5. A wheel comprising a hub, a bushing secured in the eye of said `hub having an annular recess forming a lubricant cellar or reservoir and a sectional. bushing turning on the axle with the wheel. said bushing having adjoining end portions forming thrust surfaces adapted to engage with the 'opposite side surfaces of the thrust collar on the axle and means for retaining the bushing in place in the Wheel hub.

6. A wheel and'axle construction having testimony whereof, I have hereunto set`- my hand` y EDWIN E. SLICK. l Witnesses! G. W. NEILL, i H. M. CORWIN.
